Ninety-six percent of world population increase occurs in the developing regions of Africa, Asia, and Latin America. Population growth varies from one group of countries to another as a result of differences in initial population size and differences in growth rates. … [T]he world’s less dev...
a) the population of Africa b) the global population c) the number of teenagers d) the number of infants 8) Where will population growth come from in future? a) adults b) Asia c) poor people d) children 9) What results from fertility, mortality and migration? a) population growth b)...
Sub-Saharan Africa is under-represented in global biodiversity datasets, particularly regarding the impact of land use on species’ population abundances. Drawing on recent advances in expert elicitation to ensure data consistency, 200 experts were convened using a modified-Delphi process to estimate ‘...

(Fig.4f, g). Similar gradients are observed over Africa with wetting trends over the north and drying over the south in all seasons (Fig.4). A strong JJA and SON drying is detected over south-western Australia and north-eastern Brazil (Fig.4g, h). These spatial patterns of wetting ...
One of the earliest influential genetic studies of human origins examined mtDNA variation from worldwide population sample of 147 individuals (Cann et al., 1987). The inferred maximum parsimony tree indicated that the deepest branches were in Africa and amolecular clockestimate placed the deepest spl...
By 2050 Africa’s most populous nation could have nearly 400 million people squeezed into a country one-tenth the size of the United States
We estimate the global population of Chinstrap penguins at 3.42 (95th-percentile CI: [2.98, 4.00]) million breeding pairs (Table 1) in 375 extant breeding sites, not including recent extirpations. All survey details, updated population estimates, historical benchmarks, and estimates of population...
Koebe (2020) compared Point to Polygon allocation and Voronois tessellation with an augmented Voronois method where the number of settlements within each Voronois were used as weights. They also examined two different signal propagation methods to estimate which towers are most likely to service the...
Top-down constrained age/sex structure estimate datasets for individual countries for 2020 at 100 m spatial resolution with country totals adjusted to match the corresponding official United Nations population estimates have been prepared by the Population Division of the Department of Economic and Social...
